This is a rear wheel from a military BSA WM20 or WM21. It has previously been rebuilt and painted the correct colour green. It has a new Dunlop 3.50 x 19 tyre fitted which are over £ 100 to buy now. It has the correct main shaft, half shaft and spacers included. It spins over nicely and is basically ready to fit. Just checking replacement costs, the rear sprocket, main shaft, spacers, rim, spokes etc, without the main hub would cost you over £ 400 + VAT and postage to replace, if all the bits were even available, and that does not include a tyre.
